Nitinol Wire Medical – High-Cycle Alloy for Surgical Devices
2 Million Bend Life | Biocompatible | ISO 13485 Certified
Nitinol Wire Medical for Reliable Surgical Performance
Our nitinol wire medical product is engineered specifically for high-performance healthcare applications. Crafted from a premium nickel-titanium alloy (55.8% Ni / 44.2% Ti), it offers outstanding biocompatibility and durability. This material meets ASTM F2063 standards and combines both superelastic and shape memory effects, which enable the wire to recover its shape after repeated bending. Consequently, it’s an ideal choice for surgical tools, implants, and catheter-based systems.
Polished Surface with Superior Corrosion Resistance
To meet rigorous medical standards, advanced electrolytic polishing is applied, creating a smooth and defect-free finish. This process significantly reduces friction, allowing easier navigation through vessels and tissues. Additionally, a passivation layer enhances resistance to sterilization chemicals and bodily fluids. For specialized applications, optional coatings such as oxide layers or lubricious polymers are available.
Diameter Options with Tight Tolerances
Customers can select diameters ranging from 0.1 mm to 1.0 mm, all manufactured within ±0.005 mm tolerance to ensure consistency. Thinner wires between 0.1 and 0.3 mm work best for micro-guidewires and catheter tips. Conversely, thicker wires from 0.5 to 1.0 mm provide the necessary strength for implants, orthopedic devices, and stents.
Trusted in Critical Medical Applications
This nitinol wire medical solution supports a variety of applications:
Catheters and delivery systems, offering flexibility with excellent pushability.
Stents and occlusion devices, expanding reliably at body temperature.
Guidewires, providing kink resistance and controlled torque response.
Dental archwires, delivering consistent long-term force.
Surgical robotics, capable of withstanding repetitive bending.
Implantable sensors, performing reliably under continuous fatigue stress.
Why Choose Our Medical Nitinol Wire Solution?
Notably, our wire boasts a 2 million bend cycle lifespan proven by rigorous lab testing, lasting four times longer than standard nitinol. Moreover, it meets ISO 13485 and RoHS certifications, ensuring medical-grade quality. Each batch undergoes extensive testing for transformation temperature, tensile strength (up to 1200 MPa), and elongation (up to 15%).
Customization options include transition temperatures adjustable from -20°C to 50°C, radiopaque markers for imaging, and pre-cut lengths to streamline manufacturing. Stock sizes (0.2 mm, 0.4 mm, 0.7 mm) ship within three days, while custom orders typically deliver within two to four weeks.
Furthermore, our expert metallurgical team offers design consultations, fatigue data analysis, and failure investigations to support your development needs.
